Just seeing other people's experience
In my experience, using the android client to either play locally or to control a Chromecast that the app gets into a sad state very often.
The most common failure is that the client will linger in the drop down menu and the "X" to close it does nothing. I end up going to Settings > Apps > Plex > Force Stop
a couple of times a week to make it go away. Is there something I'm missing or is this common?
